ITEM 11.  EXECUTIVE COMPENSATION

COMPENSATION OF DIRECTORS

         Our directors do not currently receive any cash compensation from us
for their service as members of our Board of Directors, although they are
reimbursed for certain travel-related expenses in connection with attendance at
Board and committee meetings in accordance with our policy.

         Each of our non-employee directors receives stock option grants under
the 1995 Non-Employee Directors' Stock Option Plan. Only non-employee directors
are eligible to receive options under the Directors' Plan. Options granted under
the Directors' Plan are intended by us not to qualify as incentive stock options
under the Internal Revenue Code of 1986, as amended.

          Option grants under the Directors' Plan are non-discretionary.
Pursuant to the terms of the Directors' Plan, each director who was serving on
the date of our initial public offering was granted on such date an option to
purchase 24,000 shares of our Common Stock. In addition, each non-employee
director subsequently elected to the Board was automatically be granted an
option to purchase 24,000 shares of our Common Stock, until the Directors' Plan
was amended in April 1999, at which time the amount of the initial grant upon
election to the Board of Directors was changed to an option to purchase 15,000
shares of our Common Stock. Each year, non-employee directors who have served as
directors for the prior year are granted an option to purchase 6,000 shares of
our Common Stock. No other options may be granted at any time under the
Directors' Plan. The exercise price of options granted under the Directors' Plan
is 100% of the fair market value of the Common Stock subject to the option on
the date of the option grant. Options granted prior to April 1999 vest ratably
over four years from the date of grant. Options granted after April 1999 are
fully vested and exercisable upon the date of grant. The term of options granted
under the Directors' Plan is ten years. In the event of our merger with or into
another corporation or a consolidation, acquisition of assets or other
change-in-control transaction, the vesting of options issued prior to April 1999
will accelerate and the option will terminate if not exercised prior to the
consummation of the transaction. At December 31, 1999, options, net of canceled
or expired options, covering an aggregate of 133,000 shares had been granted
under the Directors' Plan and 67,000 shares of our Common Stock remained
available for grant under the Directors' Plan.

         During 1999, we granted options under the Directors' Plan covering
6,000 shares to each of Messrs. Taira, Chikagami, and Chwang at an exercise
price of $10.69 per share based on the closing sales price reported in the
Nasdaq National Market on the date of grant. As of December 31, 1999, 16,000
options had been exercised under the Directors' Plan at a weighted average
exercise price of $3.04 per share, and 90,000 options were exercisable at a
weighted-average exercise price of $9.17 per share.

                        STOCK OPTION GRANTS AND EXERCISES

         The following tables show for the fiscal year ended December 31,
1999, information regarding options granted to, exercised by, and held at
year end by the executive officers listed in the "Summary Compensation Table"
above.

                            1999 STOCK OPTION GRANTS

         The exercise price of each option was equal to the fair market value
of our Common Stock on the date of grant. Mr Yeh's option was equal to 110%
of the fair market value of our Common Stock on the date of grant. The
exercise price may be paid in cash, in shares of our Common Stock valued at
fair value on the exercise date or through a cashless exercise procedure
involving a same-day sale of the purchased shares.

         The potential realizable value is calculated based on the ten-year
term of the option at the time of grant. Stock price appreciation of 5% and
10% is assumed pursuant to rules promulgated by the Securities and Exchange
Commission and does not represent our prediction of our stock price
performance. The potential realizable values at 5% and 10% appreciation are
calculated by:

     -    multiplying the number of shares of Common Stock subject to a given
          option by the exercise price per share;

     -    assuming that the aggregate stock value derived from that calculation
          compounds at the annual 5% or 10% rate shown in the table until the
          expiration of the options; and

     -    subtracting from that result the aggregate option exercise price.

         The shares listed in the following table under "Number of Securities
Underlying Option Granted" are subject to vesting. Certain of the stock options
listed in the table vest over a four-year period, 25% after one year and 2.083%
per month thereafter. Each of the options has a ten-year term, subject to
earlier termination if the optionee's service with us ceases. Under certain
circumstances following a change of control, the vesting of such option grants
may accelerate and become immediately exercisable.

         In January 1999, Mr. Yeh was awarded a short-term incentive stock
option grant for 30,000 shares of Common Stock with an exercise price of
$3.30. The grant is exercisable as follows: The first 10,000 shares shall be
exercisable on January 4, 2000. The remaining 20,000 shares shall be
exercisable at the rate of 1/48th monthly commencing January 4, 2000;
however, the following acceleration shall apply: If we return to
profitability by the end of 1999, 10,000 additional shares will be fully
exercisable on January 4, 2000; if our earnings per share reaches $0.10 per
share or higher for the year 1999, 10,000 additional shares will be fully
exercisable on January 4, 2000. We returned to profitability on a quarterly
basis during 1999 beginning with the third quarter; however, the earnings per
share target was not met. Therefore, 20,000 of Mr. Yeh's options were
exercisable on January 4, 2000 and the balance will vest over four more years
as described above.

         In January 1999, our executive officers were awarded a short-term
incentive stock option grant for shares of Common Stock with an exercise
price of $3.00. These options vested on the one-year anniversary of the date
of grant.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         On January 31, 1996, we acquired a 14% interest in a Japanese company
for approximately $939,000 paid in cash. In 1997, 1998 and 1999 this customer
accounted for 15.4% ($11.6 million), 14.7% ($10.2 million), and 8.1% ($10.0
million), respectfully, of our net revenues. This was the only customer that
accounted for more than 10% of our net revenues in 1997 and one of two customers
that accounted for more than 10% of our net revenues in both 1998 and 1999.

         Mr. Chwang is the President of Acer Technology Ventures Management LLC,
a venture capital business unit of the Acer Group, a worldwide computer,
component and semiconductor manufacturer. Several related entities, including
Acer Corporation, are our customers. In 1997, 1998 and 1999, the combined Acer
entities accounted for 6.0% ($4.5 million), 7.3% ($5.1 million) and 6.3% ($7.9
million) of our net revenues, respectively.

         Mr. Chikagami is a member of the Board of Directors of Ocean Automation
Ltd., which is one of our customers. During 1999, Ocean accounted for 0.4%, or
$541,000 of our net revenues.

         In January 1999, we loaned $75,000 to Derek Best, our Vice President,
Sales and Marketing. Under the terms of the promissory note, the loan will be
repaid over a three year period with interest-only payments made for the first
18 months of the loan, followed by interest and principal payments for the next
18 months and ending with a balloon payment of approximately $36,000. The note
is unsecured and bears an interest rate of 5.1%, the LIBOR rate in effect as of
the date that the note was signed.

         We have entered into indemnity agreements with our executive officers
and directors which provide, among other things, that we will indemnify these
persons, under the circumstances and to the extent provided for therein, for
expenses, damages, judgments, fines and settlements he or she may be required to
pay in actions or proceedings which he or she is or may be made a party by
reason of his or her position as our director, officer or agent, and otherwise
to the full extent permitted under California law and our bylaws.

          As a matter of policy, all transactions between us and any of our
officers, directors or principal shareholders will be approved by a majority of
the independent and disinterested members of the Board of Directors, and will be
on terms no less favorable to us than could be obtained from unaffiliated third
parties and will be in connection with our bona fide business purposes.
